GOLNIAN J. SEMAN United States Patent 3,261,251 TAPING GUN Colman J.Seman, 1409 Spring Lake Drive, Erie, Pa. Filed Feb. 15, 1965, Ser. No.432,758 6 Claims. (Cl. 83-649) This invention relates to dispensingmeans and, more particularly, to a dispenser for tape or the like.

It is an object of the present invention to provide an improved tapedispenser.

Another object of the invention is to provide a dispenser for coiledmaterial.

A further object of the invention is to provide a dispenser which issimple in construction, economical to manufacture, and simple andefficient to use.

With the above and other objects in view, the present invention consistsof the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawing and more particularlypointed out in the appended claims, it being understood that changes maybe made in the form, size, proportions, and minor details ofconstruction without departing from the spirit or sacrificing any of theadvantages of the invention.

In the drawing:

FIG. 1 is a side view of a dispenser according to the invention havingthe cover plate removed for better clarity;

FIG. 2 is a side view similar to FIG. 1 of the dispenser with certainparts broken away and showing the cover plate in place; and

FIG. 3 is a front end view of the dispenser with the cover plate inplace.

Now with more particular reference to the drawing, the dispenser whichmay also be referred to as a taping gun is referred to generally bynumeral 10. -The dispenser has three majors parts, (1) the main frame11, (2) the cover plate 38, which is swingably supported on the frame,and (3) the handle slide 28.

The main frame 11 is generally in the form of a plate having front coversupport block 15 fixed thereto and indicated as integral therewith. Asimilar block 16' is provided in spaced relation to the front coversupport block which provides a slot therebetween to receive the coverclamp block 43 which is fixed to the cover plate 38 and which will bemore fully described hereinafter.

The upper part of the main frame has spaced guide rails 46 and 47 whichprovide a slot 48 in which the handle 'slide 28 reciprocates. The handleslide 28 has the slide cut-off adapter 29 clamped to it by clamp screw30. These members, namely, the slide cut-off adapter 29 and the clampscrew 30, clamp the knife 31 therebetween. The knife 31 is generally inthe form of a sharpened blade of high quality steel having a very sharpedge.

The stop pin 37 is fixed to the handle slide 28 and it limits themovement of the handle slide 28 in the main frame 11 as it is urged tothe left by the spring 35, which is a tension spring fixed to the handleslide 28 by pin 36 and to the main frame 11 by pin 49.

The handle 27 is integrally fixed to the handle slide 28 and it extendsdownwardly generally parallel to the rear edge of the main frame. Theloop plunger 32 is supported on the handle 27 by means of the screw 34,thus providing a lost motion device which controls the length of theloop 26 in the tape. The screw 34 may be tightened to lock the loopplunger 32 in position on the handle so that the loop could becontrolled in length.

The tape roll 24 is supported on a boss which is in the form of acircular tape holder indicated at 13. The plunger guide blocks 12 arefixed to the main frame 11 and provide a space therebetween for the loopplunger 32 to reciprocate.

Patented July 19, 1966 Roller 19 and spaced rollers 20 and 21 are fixedto the frame and they provide a guide means for the tape. A loop 26 isprovided when the loop plunger 32 moves in and engages the tape at bight26'. The rollers 22 and 23 guide the tape to the slot below the frontcover support block 15 and the tape portion 25 extends out past the edgeof the knife.

The cover plate 38 is in the form of a plate which overlies the frontcover support block 15, a plunger guide blocks 12, boss 13, and block16. The cover plate 38 is swingably supported on pivot pin 17 and isheld thereon by means of the nut 50. The upper edge of the cover plate38 is guided by the cover plate adapter 39 which is in the form of asmall plate fastened to the lower guide rail 46 by screws 40. A returnspring 44 in the form of a leaf spring is fixed to the guide rail 46 bya screw 45. Spring 44 urges the cover plate away from guide rail 46 in aclockwise rotation. Thus, it will be seen that the cover plate 38 isheld in a plane parallel to the plane in which the main frame 11 liesand cover plate 38 can swing on its pivot pin 17. The handle 41, whichis in the form of a finger grip member, is fixed to the cover plate 38by means of screws 42.

Thus, during operation, a roll of tape will be put in the positionindicated for the tape roll 24 and the end of it will be pulled upbetween roller 19 and spaced roller 20 through high-t portion 26, overspaced roller 21 and roller 22, under roller 23, between the front coversupport block 15 and the cover clamp block 43, and on out past the endof the knife 31. The operator will then grasp the handle 41 with thetips of his fingers and lay his thumb around handle 27. He will thensqueeze the handle 27 toward the handle 41 which will move the handle 27to the dotted line position 51. This will cause a torsional force on thecover plate 38 exerted on the handle 41 which will cause it to swingaround its pivot pin 17 in a counterclockwise direction. Thus, the coverclamp block 43 will move in the tape clamp opening 16 and clamp the tapebetween the front cover support block 15 and the cover clamp block 43.

At the same time, the upper edge of the cover plate 38 will compress thereturn spring 44 against the frame shoulder 18. Simultaneously, thehandle 27 will have moved to the dotted line position 51 and the loopplunger 32 will have engaged the bight portion 26 of the tape and movedit into the form of the loop 26. The tape which was required to form theloop will have been unrolled from the tape roll 24.

When the operator releases the force on the handle, the spring 35 willreturn the handle to the full line position and the return spring 44will move the cover plate clockwise slightly about the pivot pin 17,thereby releasing the tape at the cover clamp block 43. The operator maythen stick the end of the tape to the place where it is to be attached,pull on the handle, and pull out the loop 26. This will provide a lengthof tape between the knife edge and the place where it is attached asaforesaid of a predetermined length. The tape can then be cut off by theknife 31 and the handle again moved to the dotted line position 51 whichwill rotate the cover plate counterclockwise, thereby clamping the tapeat cover clamp block 43. Another loop 26 will be formed from the roll oftape and the cutting and taping operation can then be repeated.

The foregoing specification sets forth the invention in its preferredpractical forms but the structure shown is capable of modificationwithin a range of equivalents without departing from the invention whichis to be understood is broadly novel as is commensurate with theappended claims.
